Squeaky Wheel I have been using the stuff for quite awhile. I like it because the repair does not fall out. I do not have a welder or a torch so can't compare to that. Important to have a quality iron with temp scale. Be careful with iron since impreg temp is high enough to burn base. Even through the plastic you must keep your eye on it since it likes to burn along the edge of the iron if you are not careful. Good luck
I have also used it for a long time, easier than candle, and seems to stay in. Static and the plastic sheet to protect the base tends to mean the powder gets to places you don't want it to!? if you get what i mean and you need to really let it cool before scraping it off. Really clean the area 1st.
